Leading companies Noble, Anadarko, Encana and DCP also put on strong cases, using their own operational data to show the proposal is cost effective. They should be lauded for their leadership, as should local governments and conservation groups that brought strong analytics to the hearings.

If the proposal is adopted without being weakened, it will eliminate more than 90,000 tons of smog-forming VOCs annually (the same amount produced by all the cars and trucks in Colorado) and more than 100,000 tons of methane, a highly potent greenhouse gas.

Yesterday, we covered the Colorado Air Quality Control Commission (AQCC) taking public testimony from citizens who traveled from around the state to speak in support of a groundbreaking proposal that would slash emissions of smog-forming pollutants and greenhouse gases coming from oil and gas activities.

Formal proceedings kicked off today – and will likely run through the weekend – with various parties presenting their opening cases. EDF went early in the day, providing strong evidence that the proposed rule is cost-effective and urgently needed to combat local air quality problems and climate change. We also highlighted some glaring flaws in the methodology industry opponents cooked up to show inflated costs for the rules.

The Colorado Oil and Gas Association (COGA), the Colorado Petroleum Association (CPA) and the DGS group are throwing everything they can at the rule to try to gut it. But they’re in a shrinking minority on the wrong side of history.

I’m an L.A. guy, so I like to think about things in epic story lines. And with today's launch of EDF and UCLA’s Luskin Center for Innovation new “LASER” maps (Los Angeles Solar & Efficiency Report), I think we’ve got a real blockbuster on our hands.

The LASER story opens with a team of top scientists warning us of an imminent threat – climate change – that will cause widespread disruption and human suffering if left unmitigated.

Utilizing the groundbreaking work of Dr. Alex Hall and the UCLA Institute for the Environment and Sustainability, the LASER maps illustrate what climate change is going to look like in the Los Angeles region in just a few decades.

By mid-century, the region will experience a tripling in the number of extreme heat days in the downtown and urban core, and a quadrupling in the number of extreme heat days in the valleys and at high elevations.

The plot thickens as we get a clearer sense of the communities that are most at risk – those already dealing with bad air quality, lack of adequate green space and tree canopy, poor access to public transit, and other challenges like high unemployment levels, poverty and public health hazards.

This is the part of the story where we could give up in the face of seemingly impossible odds…but that’s not how we roll in Los Angeles.

The LASER maps also introduce a powerful narrative about how we can fight back by mitigating the carbon pollution driving climate change, building community resiliency through investments in energy efficiency and renewable energy, and seizing opportunities for economic growth that reduce vulnerability.

Nearly 29,000 local jobs in solar panel installation could be created if merely 5% of the rooftop solar energy generating potential in LA County was realized.

If LA rooftops were able to capture that 5% of solar capacity they would reduce carbon dioxide emissions by 1.25 million tons, equivalent to taking 250,000 cars off the road annually.

Another LASER plot line involves energy efficiency, one of the cheapest ways to reduce carbon pollution and lower utility bills at the same time. The LASER maps show that:

Nearly 1.5 million buildings in LA County were built before energy efficiency codes went into effect, which means…

80% of all buildings in LA County have elevated potential for cost-saving, energy efficiency investments.

If this were actually a Hollywood blockbuster, we would probably cut to a final, climactic showdown and a dramatic rescue from impending doom. But unlike Hollywood, there is no pre-written ending to the climate crisis.

To mitigate the worst effects of climate change, and prepare vulnerable communities for the climate impacts already on their way, we need serious investment and deployment of clean energy and low-carbon infrastructure – particularly in those communities that will be hit the hardest.

LASER provides tools that can help elected officials and advocates pinpoint the communities that are most vulnerable to climate change, identify the region’s clean energy investment potential, and then develop policies and funding mechanism to unleash it. EDF is here to help in that effort, and look forward to supporting our friends and allies in Los Angeles who are working to make the clean energy potential profiled in LASER a real-life success story.

In the end, LASER tells a tale of threat and opportunity in Los Angeles. Now it’s time to get to work to make sure this epic has a positive ending.

Carbon is typically considered enemy number one in the context of climate-altering pollution. There is good reason why. Carbon dioxide (CO2) emitted from power plants is the leading source of U.S. greenhouse (GHG) emissions. Beyond our borders, the historic level of 400 parts per million of GHGs entering into our earth’s atmosphere was passed just five months ago – an indication of the rapid rise in human-produced emissions.

And while reducing carbon pollution is the primary goal of EDF’s climate agenda, so is minimizing methane emissions from natural gas development. That’s because methane, the main ingredient in natural gas, is a powerful GHG that can cause major climate damage in the short term. In fact, a recent analysis by many of the world's top experts on evolving climate science, the Intergovernmental Panel on Climate Change (IPCC), reports methane to be at least 84 times more potent than CO2 over the first two decades. On a 100-year timeframe, methane is at least 28 times more potent. These are noticeable changes in methane’s Global Warming Potential (GWP) from the IPCC's last assessment in 2007, with values raised from 72 to 84 and 25 to 28, roughly a 17 percent increase on a 20-year time horizon and a 12 percent increase on a 100-year basis.

IPCC’s fifth assessment (AR5) also quantitatively discusses two additional indirect effects that further increase, albeit modestly, methane's GWP. First, IPCC considers climate-carbon feedbacks and reports two sets of GWP values: one that accounts for the feedbacks and another that excludes them (they conclude that including this effect is "likely" to give a more accurate estimate of climate impacts from emissions of greenhouse gases like methane or CH4). The 20-year GWP for methane with feedbacks increases from 84 to 86, with the 100-year GWP up from 28 to 34. The explanation for this feedback is diminishing ability of oceans and soils to absorb carbon dioxide as the climate warms. As a result, as methane emissions warm the climate, more CO2 that would have historically been absorbed by the land and ocean remains in the atmosphere, causing additional warming. The second effect now quantified by the IPCC is the production of additional CO2 as CH4 is oxidized in the atmosphere, which adds another point or two to methane's GWP.

The world’s top scientists reminded us last week that the case for action on climate change has never been more urgent. And turning the corner on carbon emissions and avoiding the worst impacts of a warming world will require nothing less than a full-scale transformation of our energy system. That is a huge political, technological and cultural challenge – one that no individual, organization or country can solve on its own. It will take the leadership and collaboration of people across the world, pulling together toward a common goal.

Environmental Defense Fund (EDF) has a staff of 400 – small in the global scheme. That is why we are experts at deploying powerful networks to get results. Our success with businesses – whether it’s improving the safety of products sold at Walmart, or saving water at AT&T – all rest on our ability to tap into the knowledge, connections, and influence of our partners.

One of our most successful networks: EDF Climate Corps. Hundreds of organizations ranging from PepsiCo and Office Depot to the Chicago Public Schools and New York City Housing Authority have tapped EDF Climate Corps for energy strategies and solutions that cut costs and emissions. And best of all, our hosts and fellows are now spreading these innovations through their own networks, creating a multiplier effect that expands our impact exponentially.

In an effort to gauge where America’s power grid stands, Washington D.C.-based group GridWise Alliance evaluated grid modernization in 41 states and the District of Columbia. Texas and California tied for first place—standing far above the next runner up.

Additionally, in an effort to update Texas’ electric grid, the Public Utility Commission, Texas’ governing body for electricity, passed a resolution prompting “wires companies”(the firms that deliver energy from power plants to homes and businesses) to invest in millions of smart meters. Smart meters can help eliminate huge waste in the energy system, reduce peak energy demand (rush hour on the electrical wires) and spur the adoption of clean, low-carbon energy resources, such as wind and solar power, by managing energy demand and generation more efficiently.
